This paper describes the final part of a study on the recovery of print- and beck-dyeing wastewaters of the carpet manufacturing industry by membrane processes. These wastewaters had been previously treated separately where the print dyeing wastewaters were recovered by chemical precipitation followed by nanofiltration (NF) and beck-dyeing wastewaters were subjected to microfiltration (MF) and pH neutralization prior to NF. In this study, a co-treatment scheme after separate pre-treatment stages was adopted to simplify the overall process. The effect of mixing ratio on membrane fouling was also investigated. The co-treatment strategy was found advantageous since the number of NF units was minimized and the pH neutralization step in separate treatment of beck-dyeing wastewaters was eliminated, providing a reduction of chemical usage.

Evaluation of PCB dechlorination pathways in anaerobic sediment microcosms using an anaerobic dechlorination model Demirtepe, Hale; Kjellerup, Birthe; Sowers, Kevin R.; İmamoğlu, İpek (Elsevier BV, 2015-10-15) A detailed quantitative analysis of anaerobic dechlorination (AD) pathways of polychlorinated biphenyls (PCBs) in sediment microcosms was performed by applying an anaerobic dechlorination model (ADM). The purpose of ADM is to systematically analyze changes in a contaminant profile that result from microbial reductive dechlorination according to empirically determined dechlorination pathways. In contrast to prior studies that utilized modeling tools to predict dechlorination pathways, ADM also provides quant...
A theoretical study on vomitoxin and its tautomers Türker, Burhan Lemi; Guemues, Selcuk (Elsevier BV, 2009-04-15) In the present work, the structural and electronic properties of vomitoxin (deoxynivalenol, a mycotoxin) and all of its possible tautomers have been investigated by the application of B3LYP/6-31 G(d,p) type quantum chemical calculations. According to the results of the calculations, tautomer V-4 has been found to be the most stable one among all the structures both in the gas and aqueous phases. The calculations also indicated that, vomitoxin and V-2 possess the deepest and the highest lying HOMO levels, re...
Estimation of rate constants of PCB dechlorination reactions using an anaerobic dehalogenation model KARAKAS, Filiz; İmamoğlu, İpek (Elsevier BV, 2017-02-15) This study aims to estimate anaerobic dechlorination rate constants (k(m)) of reactions of individual PCB congeners using data from four laboratory microcosms set up using sediment from Baltimore Harbor. Pathway km values are estimated by modifying a previously developed model as Anaerobic Dehalogenation Model (ADM) which can be applied to any halogenated hydrophobic organic (HOC). Improvements such as handling multiple dechlorination activities (DAs) and co-elution of congeners, incorporating constraints, ...
Testing and analysis of different hold down devices for CFS construction Pehlivan, Barış Mert; Baran, Eray; Topkaya, Cem (Elsevier BV, 2018-06-01) This paper summarizes the findings of a two-phase study on hold down devices used in cold formed steel (CFS) structural systems. The first phase consisted of component testing and numerical analysis of hold down devices while the second phase was based on testing of CFS framed sheathed wall panels under cyclic lateral loading. Eleven monotonic and three cyclic tensile load tests were performed on seven different types of hold down devices to assess the performance of readily available hold downs and propose...
A SCREENING MODEL FOR EFFECTS OF LAND-DISPOSED WASTES ON GROUNDWATER QUALITY Ünlü, Kahraman; PARKER, JC; STEVENS, D; CHONG, PK; KAMIL, I (Elsevier BV, 1992-10-01) This paper describes a screening model for evaluating the migration of organic and inorganic contaminants leached from land-disposed wastes. The model is composed of a waste-zone release submodel, an unsaturated-zone transport submodel and a saturated-zone transport submodel. The waste-zone submodel assumes steady one-dimensional vertical flow through a uniform waste zone treated as a "stirred tank reactor". Soluble inorganic contaminants are assumed to exhibit a constant concentration in the leachate until...
